The Preparation or Regeneration of a Silver Bleach Solution by Oxidizing Ferrocyanide with Persulfate
Ferricyanide, the oxidizing agent of a silver bleach, is prepared by adding potassium persulfate to a solution of a ferrocyanide. The method may be applied for the preparation of a fresh bleach or for the regeneration of a used bleach. The preparation is simple and the ferricyanide may be produced at a substantial saving over purchasing potassium ferricyanide. Methods are included for analyzing the bleach constituents.
